Toronto police say the widow of late Toronto mayor Rob Ford has been arrested and charged with impaired driving.

Const. Victor Kwong says Renata Ford was arrested at about 6 p.m. Wednesday as she sat in a vehicle in the parking lot of a west-end shopping plaza not far from her residence.

Kwong says Ford was later charged with impaired driving and of having a blood-alcohol reading of over 80 milligrams.

He also says Ford was alone in the vehicle at the time of her arrest.

Kwong could not say when she would appear in court.

Ford's controversial late husband was mayor from 2010 to 2014. He died of cancer in March at the age of 46.
